I've simply blacklasted a bunch of moronic people lately.
If you get a domain like - xxx-[category]-free-xxx.com - DO NOT submit that domain every damn day!
I have a bunch of people with multiple category specific domains that submit a different template, different category every day. Guess what - they all get listed
Newbies - to save some bucks, get a generic name then add subfolders ie
yourdomain.com/ebony
yourdomain.com/teens
etc...
Nearly all link lists don't have a prob with sub folders, but please don't submit one theme everyday.
Ok, Rant over, back to your regularly scheduled programming
